Description
Analog ground.
5V power supply input.
Over-current threshold adjustment (Channel 1)
Soft start control for VN10 regulator. Should be tied to +5V to enable VN10 generator
Over-current threshold adjustment (Channel 2)
Non-inverted switching modulator inputs
Inverted switching modulator inputs
Bootstrapped voltage to supply drive to gate of high-side FET
(Channel 2 & 1)
Over Current Sense inputs, Channel 2 low-side
Over Current Sense inputs, Channel 2 high-side
High side gate drive output (Channel 2 & 1)
Kelvin connection to source of high-side transistor (Channel 2 & 1)
Kelvin connection to source of low-side transistor (Channel 2 & 1)
Low side gate drive output (Channel 2 & 1)
“Floating” supply input for the FET drive circuitry. This voltage must be stable and
referenced to VNN.
Negative supply voltage.
Over Current Sense inputs, Channel 1 high-side
Over Current Sense inputs, Channel 1 low-side
Feedback for regulating switching power supply output for VN10
Switching power supply output for VN10
Not connected (bonded) internally.
